The Doctrine of Imminency
The return of Christ has been expected by the Church since the time of Christ. This expectation that His return could happen at any time with no preconditions is known as the Doctrine of Imminency. The Church is told to “watch” and to “look” for his return. In the description of the Rapture of the Church, we see believers going about their daily lives working in the fields and doing other normal activities. Suddenly some are taken while others are left behind. To me this suggests they were not aware the Lord was about to return (other than knowing it could happen at any time. If any of the events described as occurring in the Tribulation had to occur before the Rapture, then Christ’s return would not be imminent. We would have recognizable events we would expect to see first. This contradicts all the Scriptures that depict His return as imminent and without warning.
The Church in the Tribulation?
In John 14:1-3, in connection with the promise of Christ, “I will come again,” the purpose of His coming is revealed to be to take believers to “my Father’s house,” by which term He describes heaven. After He meets the church in the air, He will take them to the place prepared. In contrast, at His coming to establish the millennial kingdom, all believers remain in the earthly scene. In 1 Thessalonians 5:4-10, believers are assured that they are children of light, not children of darkness. They are comforted with the promise that the day of wrath will not overtake them as a thief, as it will the world. They are promised, “For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ” (1 Thess. 5:9). In 1 Thessalonians 1:10 our hope is stated: “To wait for his Son from heaven, whom he raised from the dead, even Jesus, which delivered us from the wrath to come.” If believers are delivered “from the wrath to come,” why inflict upon them a day of wrath designed for the ungodly? Are not believers assured: “Much more then, being now justified by his blood, we shall be saved from wrath through him” (Rom. 5:9)? In Revelation 3:10 the godly church at Philadelphia is promised: “Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.” In a word, they are promised that they will be kept “from” the period of tribulation ahead. That is different from being kept “through” this time. (https://bible.org/seriespage/6-will-church-go-through-tribulation)
We see in Scripture two programs of God. First, God established the nation of Israel and revealed Himself to them. There were many faithful Jews who responded to God’s revelation and faith in the future-coming Messiah. Not all did, however. Many strayed and by the time of Christ’s first coming faith among the Jews was waning. They thought themselves righteous by virtue of lineage and thinking they were keeping the law. While much of Jesus’ ministry was to Jews, not all of it was. He spoke of “other children” and in the Book of Acts we see the Gospel going to the Gentiles which had been God’s plan all along. While some Jews came to accept Jesus as their Messiah, the majority have not. In 70 A.D. Roman soldiers sacked the city of Jerusalem and destroyed the Temple putting to an end the sacrificial system of Judaism. Jesus’ death on the cross had already rendered that system of no further value. It was to point to the ultimate sacrifice in Jesus. Once Jesus died, there was no longer a need to sacrifice in the Temple (see Hebrews 10.) Most of the Jews rejected Jesus and continued in their useless ceremonies until the Romans destroyed their Temple and dispersed them.
In the over 2000 years that have followed, we have been in the Church age where God’s focus has turned to the Church though He has not forgotten Israel. The Church age will culminate with the return of Christ and the Rapture where His church will join Him in heaven to dwell with Him forever. That is not the end though. As God always saved a faithful remnant of Jews in the OT, He will also save a remnant during The Tribulation. God’s gaze now returns to Israel and the fulfillment of His plan for them. Some Jews and some Gentiles will come to believe during the Tribulation. They are who are in view in Revelation 13:7. They will suffer for their faith but spend eternity with God. At the end of the seven year Tribulation, Christ will return again with His angels and end the reign of the Antichrist and bound up Satan and the demons and the 1000 year Millennial Kingdom will begin.
